Narrative:

I was lead aircraft (L-39) with a wingman (bae-av-8) in a ferry flight to gyy. We were both flying experimental aircraft and are required to file VFR. The weather was VMC and because of the crowded chicago airspace; we flew at 11;500 feet direct to gyy and asked for radar flight following to stay clear of controlled airspace. After climbing to cruising altitude; milwaukee departure told us that our radar service was terminated and frequency change approved. I went to gary/chicago intl tower and did a straight in to runway 12. Ground control told me to call chicago TRACON. I was then informed that I had entered class B airspace without permission. In retrospect; I should have continued to pursue radar flight following and assistance in an area with which I am not familiar. I am unsure as to how it was determined that I had violated airspace restrictions as both my wingman and I were monitoring our GPS and I showed descending beyond chicago airspace.
